Chemical sensors based on metal nanoparticle encapsulated by ligand mixture and sensor array

摘要

Metal nanoparticles are relatively in accordance with the present invention, the conductivity is low, to form a film of two or more kinds of other mixed ligand metal nanoparticles, chemical sensors, and that the metal nanoparticle sensor on the substrate which are encapsulated by the other molecule ligands having various composition ratios the chemical sensor array is provided. ; Metal nanoparticles using a mixed ligand of the present invention the sensor is improved sensitivity and response speed of the detection target, and excellent selectivity to the various sensing target, by adjusting the ligand types of mixed ligand constituting the metal nanoparticle sensor and composition application enables a highly sensitive sensor in the sensor array of the nanoparticle technology, and the design characteristics of the sensor it is possible to enable the most efficient configuration for the array of sensor systems approach analyte. Application of the array technology of such a high sensitivity sensor nanoparticles is expected to contribute significantly to the non-invasive real-time disease diagnostic technology over the breathing gas or other exudates of the human body. ; Mixing the ligand, the metal nano-particles, sensors, sensor arrays, artificial horn, artificial taste, pattern recognition
